On the Usage of Glycolic Acid
For those who use glycolic acid, it is quite effective in the process of skin care. However, the method of using it must be carefully considered in order to obtain its benefits and avoid its harm.

To start using it, it is advisable to do a skin sensitivity test first. Take a little glycolic acid product, apply it to the skin in the wrist or behind the ear, and wait for day and night. It can only be used if there is no discomfort such as redness, swelling, itching, and tingling. This is to prevent skin intolerance and allergic changes.

When using it, the frequency should be selected carefully. When first involving glycolic acid, it should be done at a low frequency. It can be done once or twice a week, until the skin is gradually getting better, and then increase the frequency as appropriate. If the skin is already delicate and sensitive, it should be advanced slowly, and it should not be rushed.

Furthermore, when using glycolic acid, the concentration is also important. For the first use, choose a low concentration, such as a concentration of 5% to 10%. When the skin tolerates it, increase the concentration. Do not use high-concentration products immediately to avoid hurting the skin.

When applying glycolic acid, the technique should be gentle. Dip an appropriate amount in the pulp of your finger and apply it gently and evenly to the face to avoid the thin skin areas such as the eyes, lips, and mouth. After applying, wait for a while until it penetrates into the skin.

After using glycolic acid, sun protection is indispensable. Because it can increase the sensitivity of the skin to light, if it is not protected from the sun, it is easy to cause pigmentation and sunburn. After daytime use, it is advisable to apply sunscreen products, and wear an umbrella and a hat when going out to avoid strong light.

All these are the essential principles for using glycolic acid. According to this, the skin can get the benefits of glycolic acid, radiant and healthy.
